Answer:

(w + 3) / 3 = 3w - 1

w + 3 = 9w - 3

6 = 8w

w = 6/8 = 3/4 = 0.75

What is the exact solution to the equation 2^2x=5^x−1 ?

Ann [662]

2^2x=5^x−1

Take the log pf both sides:

ln(2^2x) = ln(5^x-1)

Expand the logs by pulling the exponents out:

2xln(2) = (x-1)ln(5)

Simpligy the right side:

2xln(2) = ln(5)x - ln(5)

Now solve for x:

Subtract ln(5)x from both sides:

2xln(2) - ln(5)x = -ln(5)

Factor x out of 2xln(2)-ln(5)x

x(2ln(2) - ln(5)) = -ln(5)

Divide both sides by (2ln(2) - ln(5))

X = - ln(5) / (2ln(2) - ln(5))

What is the solution to −1/4(d+1)<2

kogti [31]

Answer:

$d > -9$

Step-by-step explanation:

$-\dfrac{1}{4}(d + 1) < 2$

First, multiply both sides by -4. You must also change the inequality sign since you are multiplying both sides by a negative number.

$-4 \times \left(-\dfrac{1}{4}\right)(d + 1) > 2 \times (-4)$

$d + 1 > -8$

Subtract 1 from both sides.

$d + 1 - 1 > -8 - 1$

$d > -9$

What is the y-intercept of this function?<br> f(x) = 2(x - 7)2 – 32

LUCKY_DIMON [66]

We are given the following function and want to find the y-intercept:

$f(x)=2(x-7)^2-32$

Just substitute the value x=0 into the equation to find the value of the y-intercept:

$y=2(0-7)^2-32$

Simplify

$=2(49)-32$

Simplify again

$=66$

Since the value of f(x), or y, when x=0 is 66, the y-intercept of this function is 66.

Let me know if you need any clarifications, thanks!
